Abstract
The paper discusses on the electrical conductivity on nickel-yttria stabilized zirconia (Ni-YSZ) deposition for solid oxide fuel cell (SOFC) anode. The work measures the thickness of Ni-YSZ deposition onto substrate and the electrical conductivity of the anode of SOFC. The thickness of deposition is measured using digital micrometer while the conductivity is obtained by measuring resistance using Fluke multimeter. The factors in this work are particle size and particle condition and using Taguchi method to design the experiment in Minitab 19. It was found out that optimal parameter for high thickness of deposition and high conductivity is nano particle size and uncoated particle condition. The sample using optimal parameter were measured of its conductivity in SOFC environment using furnace up to 700°C. It shows that the optimum condition for SOFC anode is at 700°C to achieved high electrical conductivity. The electrical conductivity performance of Ni/YSZ anode fabricated by electroless nickel deposition was found out comparable to previous study.
